Description

Technical Field

[0001] This disclosure relates to the field of road sweeping technology, and in particular to a sweeping roller brush and sweeping equipment. Background Technology

[0002] Road cleaning can include snow removal and garbage disposal. Road cleaning can be performed using sweeping rollers. Cleaning equipment equipped with sweeping rollers can be used.

[0003] A sweeping roller brush may include bristles, which are used to sweep roads. The distance between the sweeping roller brush and the ground can be understood as the height of the sweeping roller brush off the ground. The height of the sweeping roller brush off the ground can affect the area of ​​the ground that the bristles contact.

[0004] In related technologies, the main body of the cleaning roller brush is fixedly connected to the cleaning equipment body. When the distance between the cleaning equipment body and the ground increases, the height of a part of the cleaning roller brush off the ground increases, and the cleaning ability of the cleaning roller brush decreases. Summary of the Invention

[0005] This disclosure provides a cleaning roller brush and a cleaning device, which can at least solve the problem that when the distance between the cleaning device body and the ground increases, the height of a part of the cleaning roller brush off the ground increases, and the cleaning ability of the cleaning roller brush decreases. It can at least reduce the impact of the distance between the cleaning device body and the ground on the cleaning ability of the roller brush.

[0006] To achieve the above objectives, the first aspect of this disclosure provides a cleaning roller brush, which includes: a roller brush body fixedly connected to a rotating shaft; an ear plate including an ear plate body and an ear portion, the ear plate body being rotatably connected to the rotating shaft, the ear portion being fixedly connected to the ear plate body and used for connecting to a cleaning device body; and a pressure plate fixedly connected to the roller brush body, having an opening through which the opening passes through the pressure plate, the ear portion passing through the opening, and the opening being used to limit the range of movement of the ear portion.

[0007] Optionally, the shaft includes: a lug mounting portion for mounting lugs; and a nut mounting portion for mounting nuts.

[0008] Optionally, the ear plate body has a bearing mounting hole, the ear plate mounting part is fitted with a bearing, and the ear plate body is fitted onto the bearing through the bearing mounting hole.

[0009] Optionally, the bearing is a self-lubricating bearing.

[0010] Optionally, the nut mounting part is threaded, and the nut is a slotted nut.

[0011] Optionally, the cleaning roller brush may also include an end cap, which is fitted onto the shaft and located between the nut and the bearing.

[0012] Optionally, a first gap is formed between the brush body and the ear plate body.

[0013] Optionally, a pad is provided between the roller brush body and the pressure plate, and a second gap is formed between the ear plate body and the pressure plate.

[0014] The second aspect of this disclosure provides a cleaning device, including the cleaning roller brush of the first aspect or its various implementations, and the cleaning device may also include a cleaning device body.

[0015] In the above-described implementation of this disclosure, the ear plate is connected to the cleaning device body. When the distance between the cleaning device body and the ground increases, the distance between a portion of the cleaning roller brush and the ground also increases, for example, the distance between one end of the cleaning roller brush and the ground increases. Subsequently, under the action of external forces such as gravity, the ear plate of the cleaning roller brush rotates relative to the rotating shaft, causing the roller brush body and the cleaning device body to move relative to each other, and the aforementioned portion of the roller brush body moves closer to the ground, thereby making ground cleaning more efficient. Correspondingly, the impact of the distance between the cleaning device body and the ground on the cleaning ability of the roller brush is reduced. Attached Figure Description

Detailed Implementation

[0024] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0025] In this disclosure, the terms "first," "second," etc., are used to distinguish one element from another and do not imply any order or importance. In the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0026] In related technologies, the main body of the cleaning roller brush is fixedly connected to the cleaning equipment body of the cleaning device. When the distance between the cleaning equipment body and the ground increases, the height of one end of the cleaning roller brush from the ground increases, and less bristle will contact the ground at this end of the cleaning roller brush, thus reducing the cleaning ability of the cleaning roller brush.

[0027] To at least address some of the deficiencies described above, this disclosure provides a cleaning roller brush and a cleaning device. For ease of understanding, embodiments of this application will be described below with reference to the accompanying drawings.

[0028] See Figures 1 to 6 This application provides a cleaning roller brush, which includes: a roller brush body 10, with a rotating shaft 11 fixedly connected to it; an ear plate 20, including an ear plate body 21 and an ear portion 22, the ear plate body 21 being rotatably connected to the rotating shaft 11, the ear portion 22 being fixedly connected to the ear plate body 21 and used to connect to the cleaning device body; and a pressure plate 30, fixedly connected to the roller brush body 10, with an opening 31, the opening 31 penetrating the pressure plate 30, the ear portion 22 passing through the opening 31, and the opening 31 being used to limit the movement range of the ear portion 22.

[0029] It should be noted that the roller brush body 10 is fixedly connected to the rotating shaft 11, the ear plate 20 can rotate around the rotating shaft 11, and the ear portion 22 of the ear plate 20 can be connected to the cleaning device body of the cleaning device (e.g., fixedly connected). In this case, the roller brush body 10 can rotate relative to the cleaning device body of the cleaning device. Figure 3 and Figure 4The diagram illustrates the state in which the roller brush body 10 and the ear plate 20 rotate relative to each other. When the cleaning equipment experiences bumps during operation, one end of the roller brush body 10 moves away from the ground. Subsequently, under the influence of external forces such as gravity, the roller brush body 10 rotates relative to the cleaning equipment body, causing this end of the roller brush body 10 to move closer to the ground. The roller brush body 10 is typically equipped with bristles (not shown in the diagram). The larger the area of ​​the ground contacted by the bristles, the stronger the cleaning ability; the smaller the area of ​​the ground contacted by the bristles, the weaker the cleaning ability. As can be seen from the above description, although bumps can worsen or reduce the cleaning ability, the cleaning ability gradually increases as the roller brush body 10 rotates. This solves the problem of decreased cleaning ability when the distance between the cleaning equipment body and the ground increases, reducing the impact of the distance between the cleaning equipment body and the ground on the roller brush's cleaning ability and improving cleaning efficiency.

[0030] It should be further explained that the opening 31 of the pressure plate 30 restricts the range of movement of the ear 22, thereby limiting the range of movement of the roller brush body 10 relative to the cleaning device body. This range of movement may include the range of rotation. For example, the unidirectional rotation angle of the ear plate body 21 relative to the rotating shaft 11 can be limited to between 0 and 10 degrees. This unidirectional rotation can be clockwise or counterclockwise. By limiting the range of movement, the possibility of the roller brush body 10 colliding is reduced, thereby improving the service life of the cleaning roller brush.

[0031] Furthermore, the rotating shaft 11 includes: an ear plate mounting portion 111 for mounting the ear plate 20; and a nut mounting portion 112 for mounting the nut 40.

[0032] It should be noted that the ear plate 20 can be fitted onto the ear plate mounting part 111, and the nut 40 can be fitted onto the nut mounting part 112. By setting the nut 40, the ear plate 20 can be reduced or even prevented from detaching from the rotating shaft 11, thereby improving safety and the service life of the cleaning roller brush.

[0033] Furthermore, the ear plate body 21 has a bearing mounting hole 211, and the ear plate mounting part 111 is fitted with a bearing 50. The ear plate body 21 is fitted onto the bearing 50 through the bearing mounting hole 211.

[0034] It should be noted that the bearing 50 can be used for lubrication, which makes the rotation of the ear plate body 21 relative to the ear plate mounting part 111 smoother, reduces the influence of frictional resistance on rotation, provides rotational flexibility for the cleaning roller brush, and reduces equipment wear.

[0035] Furthermore, bearing 50 is a self-lubricating bearing.

[0036] It should be noted that bearing 50 can be implemented using a self-lubricating bearing, but this is merely an example. In practice, bearing 50 can be implemented using a bearing component with lubrication function.

[0037] Furthermore, the nut mounting part 112 is threaded, and the nut 40 is a slotted nut.

[0038] It should be noted that the slotted nut can have a slot, which can be used to make the connection between the nut 40 and the nut mounting part 112 more secure, thereby improving the service life of the cleaning roller brush.

[0039] Furthermore, the cleaning roller brush also includes an end cap 60, which is sleeved on the rotating shaft 11 and located between the nut 40 and the bearing 50.

[0040] It should be noted that by setting the end cap 60, the collision between the nut 40 and the bearing 50 can be reduced, the probability of the nut 40 dislodging from the rotating shaft 11 can be reduced, and the safety and service life of the equipment can be improved.

[0041] Furthermore, refer to Figure 6 A first gap 70 is formed between the main body 10 of the roller brush and the ear plate body 21.

[0042] It should be noted that by setting the first gap 70, the rotation of the ear plate 20 can be made more flexible and smooth, reducing friction and wear, and improving the service life of the equipment.

[0043] Furthermore, refer to Figure 6 A pad 80 is provided between the roller brush body 10 and the pressure plate 30, and a second gap 90 is formed between the ear plate body 21 and the pressure plate 30.

[0044] It should be noted that by setting the pad 80, the friction between the pressure plate 30 and the roller brush body 10 can be reduced, forming a second gap 90, which makes the rotation of the ear plate 20 more flexible and smooth, reduces friction resistance and wear, and improves the service life of the cleaning roller brush.

[0045] Based on the above, this disclosure also provides a cleaning device, including the cleaning roller brush in the above embodiments.

[0046] Since the cleaning device provided in this embodiment has the cleaning roller brush provided in any of the above embodiments, the cleaning device has all the beneficial effects of the cleaning roller brush provided in any of the above embodiments, which will not be repeated here.

[0047] The spreading system and spreading machine provided in this disclosure have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this disclosure. The descriptions of the embodiments above are only for the purpose of helping to understand the core ideas of this disclosure. It should be noted that those skilled in the art can make various improvements and modifications to this disclosure without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this disclosure.
